It is reported that the oldest person is China health qigong master Li Qingyuan. Born in the 18th year of Qing Emperor Kangxi, he died in the 24th year of the Republic of China (1679- 1935) at the age of 256. Li Qingyuan, whose ancestral home is Yunnan, lived in Kaixian County, Sichuan Province in his 90s until his death. Liu Chengxun, a native of Kaixian County, Sichuan Province, paid a special visit to the old man on 1925. Liu's interview and reminiscence articles were published in the sixth issue of Qigong magazine 1986, and there was also 1000 words of Immortality dictated by the birthday girl. After the death of the old man, some newspapers in Beijing reported on the topic of "the longest-lived person on earth", but it was doubted and denied by Guinness World Records at that time, and was later confirmed by many textual researches.
